        <footnote id="F1">Each performance unit represents a contingent right to receive one share of the UTI Common Stock, 60% of which vest based on revenue for the fiscal year ending September 30, 2024 and 40% of which vest based on income (loss) from operations for the fiscal year ending September 30, 2024, the sum of which will be adjusted by a compound annual total shareholder return (&quot;TSR&quot;) modifier (which modifier may result in the adjustment of the performance units by up to 25% either upward or downward). For purposes of determining the TSR, the change in the price of the UTI Common Stock is based upon the 30-trading day average closing stock price (i) ending on and including the grant date, and (ii) ending on and including the last day of the Performance Period.  The amount represents the maximum number of shares that may be delivered pursuant to the award, which is 187.5% of the target number of shares.</footnote>
        <footnote id="F2">Each restricted stock unit represents a contingent right to receive one share of UTI Common Stock.</footnote>
        <footnote id="F3">The restricted stock units vest in three equal annual installments beginning on December 8, 2022.</footnote>
